/**
 * Process safety nets
 *
 * The server handles many independent operations in a row. An error that
 * surfaces outside a handler — from an SFTP channel, a timer, a promise
 * nobody's watching — terminates the whole Node process by default: the
 * client loses not one call but the entire session with every profile.
 * Here such an error becomes a log entry instead, and the server keeps
 * responding.
 *
 * The one exception is a closed channel to the client: there's no one left
 * to work for, and no reason to stay in memory.
